I purchased a PS3 on ebay for £11 spares or repair, it is a 40gb fat and it was YLOD when i got it. I spent a couple of hours on it and tried the heatgun repair on it and it worked and has brought it back to life. How long it will last i have no idea but for £11 and a couple of hours work if i get a few months out of it i will be happy. I know some people wont agree with the heat gun but i thought as it only cost £11 and was dead anyway it was worth a try. If you take your time the PS3 is quite easy to strip down, if you build computers you can rebuild a PS3 there is nothing really scary.
